Not able to connect VM to internet.

[chil7]

Hey there,

 

I made a VM on a shared server. The default OS from the boot device on the Unraid account is Ubuntu 20.04 LTS. I received an IP address, gateway and subnet mask from my IT department. I changed the netplan file to set the IP address for the VM, but I am not able to connect to internet. I checked my firewall and it is inactive. Maybe the network settings are not set up correctly. Any feedback would be appreciated, thanks.

If I understand correctly you are virtualizing Unraid? Going to move this to the correct place to see if someone can help you.

It seems like I was posting it in the correct place. That forum is for configuring VMs. Which is what I am trying to do. Is there something I am misunderstanding?

[JorgeB]

Maybe I misunderstood, what does this mean?

Are you trying to install Unraid as a VM running on Ubuntu or the other way around?

[chil7]

I installed Ubuntu on a VM I made on my Unraid account.

 

To be more specific: When I made a new VM in the Unraid OS, I chose to boot from a shared iso which had the Ubuntu OS.

Ok, I'll move it back, the network settings you show are for Unraid, I assume Unraid has network access, just not the Ubuntu VM?

Post a screenshot of that specific VM's config, or paste the xml code.

Ok sounds good. 

 

Yes, Unraid has network access, but the Ubuntu VM does not have internet access.

Here is the netplan config file that I altered in the Ubuntu VM. I added my IP address, gateway and DNS server.

I can ping to the Unraid server at 131.252.223.178. But I cannot ping the gateway (131.252.223.177).

 

Looking at the routing, it shows it goes from my IP (131.252.223.182) to the bridge (br0) at 131.252.223.176/29 

 

Am I supposed to configure br0 in my VM?

Here you go, sorry about that.

[JonathanM]

Are you sure the version of Ubuntu you are using includes the virtio-net driver? Have you tried other network model options?

[chil7]

I think the main problem was that I did not install the qemu guest agent. So I ran the command to install it on my VM and now my VM shows the interfaces, where it said "Guest agent not installed" before.

 

 

So now I can download packages but I still cannot ping out to my gateway or anywhere else. I am confused as to why I cannot ping out but can download files.

I checked my virtio drivers and this was the output

Further investigation of my network drivers:

Also found this, which shows driver is virtio_net:
